6 Claims. (Cl. 292336.3)

This invention relates to a handle which is particularly adapted for usewith barrel bolts, catches and similar fastening devices.

This application is a divisional application of application Serial No.553,828 filed December 19, 1955, now- Patent No. 2,843,412.

It is an object of my invention to provide a new and improved handleconstruction for the plungers of barrel bolts and catches, which handleconstruction is particularly adapted for use with plungers of relativelysmall diameter. The handle constructions which are presently in use onsuch devices do not adapt themselves to eflicient use in connection witha small diameter plunger.

It is a further object of'my invention to provide such a handle which isstrong and which is also easy to assemble and to attach to the plunger.The parts used to form my device and their method of assembly andattachment to the plunger and to each other are novel in the art.

It is more particularly an object of my invention to provide a handle ofthe type described which attaches to the plunger in such a manner thatit does not enlarge the diameter of the plunger and thus, in the case ofa barrel bolt or catch, does not interfere with the reciprocal movementof the plunger along the barrel.

It is also among the objects of my invention to provide a handle of thetype described in which only one fastening operation is required toassemble the handle and simultaneously secure it to the plunger. Thefastening operation may comprise a simple spot welding of two contactingsurfaces.

My invention also comprises such other objects, advantages andcapabilities as will later more fully appear and which are inherentlypossessed by my invention.

While I have shown in the accompanying drawings preferred embodiments ofmy invention, it should be understood that the same are susceptible ofmodification and change without departing from the spirit of myinvention.

Referring to the drawings,

Fig. 1 is a perspective view of a complete double-action barrel boltseparated from the receiving means, showing my handles in use;

Fig. 2 is a front elevational view of the handle half of my invention;

Fig. 3 is a side elevational view of the handle half shown in Fig. 2;

Fig. 4 is a front elevational view of a complete handle formed bycombining two of the halves shown in Figs. 2 and 3.

One embodiment which has been selected to illustrate my invention isadapted to be used in connection with a conventional spring-action catchor barrel bolt. The barrel bolt structure includes a plate 10, the lowerend of which is curved back on itself to form a cylindrical hollowbarrel 11, which extends along one edge of the plate 10.

Mounted within the center portion of the barrel 11 2,938,746 PatentedMay 31, 1960 is a coil spring 12, the opposite ends of which exertoutwardly directed pressure against the inner ends of a pair ofelongated cylindrical plungers 13, which are reciprocally mounted withinthe barrel 11, adjacent the opposite ends thereof. The barrel 11 isprovided adjacent its ends with a pair of substantially L-shaped slots14,.

the longer portion of which extends longitudinally with respect to thebarrel 11.

The coil spring 12 normally urges the plungers 13 so that their endsextend outwardly from the opposite ends of the barrel 11. The slots 14are provided for connection of the plunger handles which permit manualretraction of the plungers 13 back into the barrel 11 against thepressure of coil spring 12 to release the catch.

The above described structure is that of a conventional.

double action barrel bolt or spring biased catch. Such.

devices are also constructed with only a single plunger, as well. Thenovelty of my invention lies in the con-- struction and method ofattachment of the handle to the: plunger or plungers.

With my invention, the number of parts forming they handle has beenreduced to two identically formed handle halves 40, which are preferablyformed of metal. Each of the handle halves 40 has an integral upperportion 41, which is substantially circular in shape and has an integralsubstantially right angular flange 48 extending around one half of itsperiphery. The center of the upper portion 41 is provided with yarecessed hemispherical portion 42.

The bottom surfaces of the hemispherical portions 42 are provided withsmall slightly flattened areas at their centers, which are brought intoclose proximity to each other when two handle halves 4d? are assembledto form a complete handle. The handle halves 40 can thus be permanentlyattached to each other by spot welding the,

The plunger 13 of the barrel bolt is provided with a circumferentialgroove 20, which extends to a depth at least equal to the thickness ofthe arcuate portions 44. My handle is attached to the plunger 13bymounting the arcuate portions 44 of the two handle halves 40 in thegroove 20 on opposite sides of the plunger 13. The handle halves 40 arethen fastened together by bending the bend tabs 45 around the straightportions 43. Additional fastening means may also extend through thehemispherical portions 42 or such portions may be spot welded togetherin the manner described above.

My handle is thus attached to the plunger 13 so that the straightportions 43 extend through the slot 14 in the barrel 11. The portions 41may easily be gripped by the fingers to move the handle inwardly againstthe action of the coil spring 12. When the straight portions 41 reachthe inner end of the longitudinal portion of the slot 14, the end of theplunger has been withdrawn into the end of the barrel 11. If the plungeris to be locked in retracted position, the straight portions 43 aremoved into the connecting transverse portion of the slot 14, the edge ofwhich prevents outward movement of the handle. The plungers 13 areadapted to removably fit within the hollow portions 46 of a second plate47, shown in the upper part of Fig. 1, or any other suitable receivingmeans.
